I don't snack.
Anyway, if it weren't for being drunk off my ass at 3am a couple days out of the week, I probably would never eat at any fast food chains. It helps that I don't smoke weed lately, too. But I don't ever forbid myself from eating a particular food if I really want to. Sometimes, I get a real strong craving for a 3-piece leg and thigh meal with mashed potatoes and gravy and a side of coleslaw from KFC. That includes biscuits, of course. If there were dead babies in it, I'd still eat it 'cause it tastes so good.
